Show HN: ZigNet: How I Built an MCP Server for Zig in 1.5 Days
AI is great and all, but it can't keep up with Zig's breakneck development pace. So I wondered: what would it actually take to build my own? Turns out, with a hybrid deterministic/stochastic approach, an RTX 3090, and 4.5 hours of training, I created a specialized LLM that runs on a regular laptop.
In this technical retrospective (2025), @Fulgidus shares practical architectural lessons learned from running, scaling, or migrating production software under lean constraints.
Core Principles for Independent Builders:
Defaulting to simpler architectures (such as monolithic frameworks, SQLite, or managed VPS) prevents early engineering bankruptcy.
Evaluating true compute and egress costs reveals that high cloud bills can often be slashed by 80%+ through judicious re-platforming.
Code you write at 2 AM as a solo engineer must be easy to debug six months later without complex microservice dependencies.
Community Debate Themes:
HN engineers debated the tradeoffs between cloud convenience and raw server economics, database indexing strategies, and resisting premature architectural complexity.
